We have recently discovered self-assembled chains of C60 molecules contained within single wall carbon nanotubes (SWNTs). Using in situ transmission electron microscopy studies, we show a route by which such ‘peapod’ structures can be synthesized. The results indicate that exterior C60 molecules arrive at the nanotubes from the vapor phase and subsequently enter, presumably through open ends or sidewall defects. The methods discussed in this work provide a means for the bulk production of these molecular assemblies.
